Abstract AITranslate

Study is made on the condition and analysis method for oxygen determination from doped tungsten powder by pulse heating coulomb testing.The results indicated that the analytical heating temperature of doped tungsten powder controlled by heating current can be identical with that of the tungsten powder.Normally,the heating current is 750~800 A,analysis carrier gas flowrate is 150 mL/min.The flux should be wrapped by Ni-foil.The relative standard deviation is 2%.The method is applicable for production analysis.
